DISH -WASHING MACHINE.

-Application filed March 12, 1909. Serial No. 482,891,

Be it known that I, REBECCA A; HENRY, a citizen ofthe United States of America, re-

siding at Irwin, in the county of Westmoreland and State of Pennsylvania, have invented certain new. and useful Improvements in Dish-Washing Machines, of which the following is a specification, reference being bad therein to the accompanying draw- I This invention relates to a dish washing macliine, and the invention has for its primary object to provide a machine wherein support.

novel means 'are'employed for revolving adish support in a tub, pan or receptacle filled with hot water or a cleansing solution,

capable of-removin 'rease, dirt, and foreign matter from Another object of'this invention is to provide .a machine of the above t pe with a revoluble dish support that can e revolved in a receptacle filled with water, then elevated and'revolved above fthe receptacle to dry the dishes, after having been washed.

A further object ,of this invention is to provide a simple, durable and easily operated dish washing machine wherein a novel mechanism isemployed for revolving dishesin a receptacle and then elevating said dishes to facilitate'the removal of the same from the rece tacle.

The a ove objects are attained by a machine that will be hereinafter described in i application, wherein there is illustrated the detail and'then specifically. pointed out in be hadto the "drawings forming part of this referred embodiments of the invention, but it is to be understood that the details of construction can-be varied or changed without departing from the spirit or scope of the in-.

v vention.

In the drawings, Figure 1 is a vertical sectional viewof the machine, Fig. 2 is a plan of the same. Fig. 3 is a long tudinal view of the motor spring, showing a part ofthe sleeve which carries the arbor for the spring and also showing a part of the s rin support-in section, and F igat is'ja etai plan view of the motor sprm and ,pin for one end in section.

.The reference numeral 1 designatesa cylindrical receptacle or -tub having the botis es placed upon the awl and ratchet mechanism, the ar or an securing of the spring being. shown 'tomthereof provided with a drain openin 2 normally closedvby a plug 3. Suppoite by the bottom of the receptacle is a central vertical tubular post 4: and slidably mount ed upon said-post,--is a sleeve 5 having the upper end thereof closed, as at 6, while the "Specification of Letters Patent. I Patented Dec. 28, 1909, 1

lower end thereof extends into proximity to I the bottom of the receptacle 1, and is pros vided with acircular platform or tray 7.

This tray is provided "with a plurality of radially disposed apertured bars 8', having the outer ends thereof connected by a-rim 9. The tray'is adapted to support dishes, as

plates and saucers, and for holding cups and v in its upper end with a key-socket 18 This sleeve at its lower end carries a disk 18 provided on its under face with aspringpressed pawl .18 which engages with a,

ratchet Wheel 18 fixed on the arbor 13 be- .neath the disk- 18. A spring 15 has its innerend attached to the winding-sleeve 18* and its outer end attached to a post 16 carried by a transverse support 17 mounted on the upper open end'of the receptacle 1. To hold the support 17 against rotation on the receptacle, the latter is provided onopposite sides thereof at its upper end with lugs 19 whichare engaged by depending ends 20 of the support 17.

21 designates acoil spring encircling the lower end of the tubular post 4 between the bottom of the, receptacle and the circularv tray 7 said spring being employed to elevate the tray and the sleeve 5, after the dishes have been washed. The spring .21 is held under tensionfby a pawl .22 pivotall-y' supported by .a bracket 23 carried by the bottom of the receptacle. The upper end of the pawl .is hook shaped, as at 24, to engage the u per .convolutlon of the spring 21,

while the ower'end of the awl is pivotally connected to .a rod 25 exten ing throu h the bracket 23 adjacent to the bottomoft ere-- 1 One end of the rod 25 is pivotally cept'acle. connected, as. at 26, to a lever 27 fulcnumed upon a bracket 28, carried by the umer side of the receptacle 1. The hook-sh: ed upper end 24: of the pawl 22 is normal y held in engagement with the upper convolution of the spring 21 by the lever 27, the normal position of the latter being that shown in Fig. l. The upper portion 29 of the lever 27 is bent upwardly, and protrudes through a slot 30 provided therefor in the support 17 The opposite end of the rod 25 extends through the base of the tubular post 4. and is connected to a chain or cable 31 extending back into the post, the chain or cable 31 passing over the sheave revolubly supported at the lower end of the post at. The

opposite end of the chain or cable'3l is connected to a .brake lever 33 pivotally mounted as at 34, in a slot 35 provided therefor in the post- 4. The brake lever 33 is provided with a shoe 36 for fri ctionally engaging the inner side of the sleeve 5, and said shoe is normally held out of engagement with the sleeve 5 by a coil spring 37, arranged above the brake lever, and connecting the upper end thereof to the post 4. d

The receptacle or tub 1, having been filledwith water or a cleansing solution, my machine is operated in the following manner,- The dishes to be cleansed are assembled upon the tray 7 and the arms 10, these ele ments constituting a dish support. The spring 15 is then placed under tension or wound by the key 14 and upon the spring being released, by removing the key 14, said spring gradually unwinds and revolves the sleeve 5, causing the dishes to be thoroughly; agitated by the water within the receptacle 1 and cleansed. As the spring 15 unwinds, or expands, the outer convolution thereof contacts with the portion 29:0f the lever 27, shifts said lever and the rod 25, to move the pawl 22, releasing the spring 21, and allowing saidspring to elevate the sleeve 5, the dish support carried thereby, together with the support 17. Immediately upon the spring 21 being released, the rod 25 pulls upon the chain or cable 31 and causes the brake-shoe 36 to frietionally engage the-inner side of the sleeve 5, and prevent too rapid an elevation of said sleeve and the dish support thereof. After the dishes have been elevated, they can be easily-removed, or the support 17 held, and the spring 15 can be rewound to revolve the sleeve 5 and dry the dishes carried by the tray 7 and the arms 10. The opening 2 and the plug 3 of the receptacle allows the soiled Water to -be easily removed. I

The machine can 'be used for sterilizing sur ical instruments and the time of 1m- -mersion of either instruments or dishes, is

regulated by the size of the spring 15 used in connection with the machine.

The brake lever 33 is employed to prevent a sudden movement of the sleeve 5 when the spring 21 is released, and in some instances can be dispensed with.

Having now described my invention, what I claim as new, is I 1. In a washing machine, the combination with a receptacle, of a central tubular post arranged in said receptacle, a sleeve movably mounted upon said post, a dish support carried by said sleeve, a transverse movable support arranged upon the upper end of' said receptacle and adapted to be temporarily held in engagement therewith, an arbor carried by the upper end of said sleeve and extending through the said transverse support, a spiral spring carried by said transverse support and connecting with said sleeve for revolving said sleeve, a coil spring encircling the lower end of saidpost between said receptacle and saiddish.support for elevating said sleeve, a pawl pivotally supported wlthin said receptacle for-retainlng said coil spring under, tension, a rod connecting with said pawl, a lever-connecting with said 'rod ,and extending through said transverse support to be actuated by an unwinding movementof said spiral spring for moving said pawl and releasing said coil spring to elevate said sleeve and the dish-support, and means arranged within said tubular post and actuated by said rod for retarding the elevation of said sleeve and the dish support, substantially as described.

2. In a washing machine, the combination with a receptacle, of a central tubular post arranged in said receptacle, a sleeve movably mounted upon said post, a dish support carried by said sleeve, a transverse movable support arranged upon the upper edges of said receptacle and adapted to be temporarily held in engagement therewith, means carried by said support for revolving said sleeve, a coil spring encircling the lower end of said post between said receptacle and said dish support .for'elevating said sleeve, a pawl pivotally supported within said receptacle for retaining said coil spring under tension, a rod connecting with said pawl and a lever eonnectin with said rod and extending through saif In testimony whereof I aifix mysignature in the presence of two witnesses.-
